Junio, thanks for encouraging feedback and for catching the *-isms. What
you propose is good (and we also automatically fix error when there was
no config.mak - it was working but cp was giving an error to stderr but
script was continuing normally).
I would amend your squash the following way:
* `test -f` -> `test -e`, because -f tests whether a file exists _and_
is regular file. Some people might have config.mak as a symlink for
example. We don't want to miss them too.
Please find updated patch below:
---- 8< ----
From: Kirill Smelkov <kirr@xxxxxxxxxx>
Subject: [PATCH] t/perf/run: Don't forget to copy config.mak.autogen & friends
to build area
Otherwise for people who use autotools-based configure in main worktree,
the performance testing results will be inconsistent as work and build
trees could be using e.g. different optimization levels.
See e.g.
http://public-inbox.org/git/20160818175222.bmm3ivjheokf2qzl@xxxxxxxxxxxxxxxxxxxxx/
for example.
NOTE config.status has to be copied because otherwise without it the build
would want to run reconfigure this way loosing just copied config.mak.autogen.
